Wire-rope twist-preventing device for high mast lamps

Abstract

The invention relates to a wire-rope twist-preventing device for high mast lamps, which relates to a high-mast-lamp structure technique. The upper part of a lamp mast is provided with a vertical elevating groove, a lamp panel is transversely arranged in the elevating groove, a rope-dividing tray is arranged in the lamp mast below the lamp panel, the lower end of the rope-dividing tray is connected with a main steel wire rope, the upper end of the rope-dividing tray is connected with a plurality of vice steel wire ropes, and each vice steel wire rope respectively passes through a vertical through hole of the lamp panel; the top of the lamp mast is provided with pulleys (the number of the pulley is same as that of the vice steel wire rope); and the rope-dividing tray is provided with a cable-passing hole. The device provided by the invention is characterized in that plane bearings (the number of the plane bearing is same as that of the vice steel wire rope) are uniformly distributed on the lamp panel, each plane bearing is respectively provided with a guide wheel, and each vice steel wire rope after being protruded from the upper end of the lamp mast is fixedly connected to the top of the lamp panel after respectively passing a corresponding pulley and a corresponding guide wheel. By using the device provided by the invention, the occurrence of a phenomenon that a cable and the vice steel wire rope are mutually twisted when the cable goes up or down can be effectively prevented.

Description

technical field [0001] The invention relates to the structure technology of high mast lamps, in particular to the field of control technology for controlling the lifting and lowering of lamp panels of high mast lamps. Background technique [0002] The lift type high pole lamp is composed of a lamp panel (on which lamps are mounted), a lamp pole, a lifting mechanism, and an electrical device. The lifting mechanism of the lifting high pole lamp is driven by the electric motor, (electromagnetic brake type) worm gear reducer, safety coupling, main wire rope, auxiliary wire rope, rope divider and movable pulley block to drive the lamp panel to rise and fall. [0003] During the rising process of the lamp panel of the high pole lamp, the three auxiliary steel wire ropes and the cables are lowered at the same time, which are easy to get mixed up and cause harm to the cables. [0004] At present, the counterparts adopt to install three plane bearings on the rope splitter connected ...

AI Technical Summary

Problems solved by technology

[0003] During the rising process of the lamp panel of the high pole lamp, the three auxiliary steel wire ropes and the cables are lowered at the same time, and they are easy to get mixed up, which will cause harm to the cables. If the cables are aging, broken, or leaking electricity, they will short circuit with the steel wire ropes and burn the steel cables, causing safety hazards.

[0004] At present, the industry adopts the method of installing three plane bearings on the rope divider connecting the main wire rope and the three auxiliary wire ropes to adjust, but the desired effect cannot be achieved.

When the three auxiliary steel wire ropes and cables are mixed together, the plane bearing cannot be adjusted according to its own performance, and there is no way to adjust it manually, because the lifting mechanism and electrical device are installed in the light pole, and people cannot enter the pole due to space constraints. debug
